The aim of the present paper is an attempt at viewing the European Union’s and Russia’s policies towards Ukraine from the perspective of crises experienced by the country and the whole area of Eastern Europe, as well as regarding the issue of security. Russia – Ukraine war drives EU decision-makers into focusing merely on stabilization of the eastern neighbourhood. On the other hand, Russia destabilises the internal situation in Ukraine and eastern neighbourhood of the EU by supporting Donetsk and Luhansk separatisms. Eastern Europe is a neighbourhood mutually shared by the EU and Russia. As a consequence, the area is vitally important for Russia and, to a lesser degree, signiﬁcant for the EU. The analysis will encompass the consideration of the following research questions: Will the Ukrainian crisis result in a change of geopolitical situation in Eastern Europe? Will Ukraine become an unstable area, an area experiencing a next “suspended conﬂict”? Has Russia’s policy towards Ukraine reached its objectives? Is the current EU policy a token of EU decision-makers’ lack of vision as regards the prospective EU-Eastern Partnership countries’ (especially Ukraine) relations?
